SEWING-MACHIN E ATTACHMENT.

Specification of Letters 2atent.

Patented Oct. s, 1918;

To all whom it may concern:

Be it known that I, HARRY WV. Bncxwrrn, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Sewing-Machine Attachments, of which the following is a specification.

My invention relates to sewing machine attachments and consists in the novel features herein shown, described and claimed.

My object is to make an attachment for use in sewing machines for repairing shoes and similar heavy work, so that the presser foot may be optionally connected to reciprocate with the needle so that the work being stitched may be moved forwardly, backwardly, or sidewise, as desired, from stitch to stitch.

Figure 1 is a front elevation of a sewing machine equipped with my attachment and in operation, as seen looking in the direction indicated by the arrow 1 in Fig. 3.

Fig. 2 is a fragmentary rear elevation as seen looking in the direction indicated by the arrow 2 in Fig. 3.

Fig. 3 is an enlarged fragmentary end elevation as indicated by the arrows 3 in Figs. 1, 2 and 4.

Fig. 4 is a fragmentary elevation upon an enlarged scale upon a plane parallel with Fig. 2 and as indicated by the arrow 2 in Fig. 3.

Fig. 5 is a vertical cross-section on the line 55 of Fig. 1.

The presser foot 1 is rotatably mounted upon the lower end of a sleeve 2, said sleeve being slidably mounted in the head 3, and the needle shaft 4 is slidingly mounted through the sleeve 2 and operated by the walking beam 5. An arm 6 extends laterally from the upper end of the sleeve 2 and a button 7 is secured to the outer end of this arm for use as a handle in raising and lowering the presser foot 1. The clamping plate 8 rests on top of the button 7. Jaws 9 and 10 extend downwardly and inwardly from opposite edges of the clamping plate 8 to engage under the rim of the button 7, and a setscrew 11 is screw-seated downwardly through the center of the plate 8 to engage the center of the upper face of the button 7 and draw the jaws 9 and 10 tightly up against the rim. An arm 12 extends upwardly from the back edge of the plate 8 at right angles thereto. A plate 13 is pivotally connected to the upper end of the arm 12 by a rivet let, said rivet extending through the plate 13 substantially at its center. A slot 15 is formed in one side of the plate 13. A setscrew 16 is screw-seated through the arm 12 in position to enter the slot 15 so that when the set-screw 16 is loosened the plate 13 may be swung to a vertical position with the screw 16 in the slot 15 and then the screw may be tightened to hold the plate 13 rigid. A hook 17 extends horizontally from the upper end of the plate 13 into the plane of the end of the walking beam 5 and needle shaft A, so that when the plate 13 is swung to its vertical position and locked the hook 17 is above the Walking beam and needle shaft and the reciprocation of the needle shaft will raise the presser foot 1 at each upstroke of the needle.

The presser foot 1 is swiveled, as before suggested, upon the lower end of the sleeve 2 and when the attachment is in place for operating the presser foot the operator may place a shoe or the like upon the horn 18 of the sewing machine and the presser foot will raise from the work at each upstroke of the needle and the operator may step the work forwardly and backwardly and sidewise to make stitching like hand work.

When it is desired to make a straight seam the set-screw 16 is loosened and the plate 13 turned to a horizontal position, as shown in dotted lines in Fig. 1.

Various changes may be made in the details of construction without departing from the spirit of my invention as claimed.

I claim:

1. A sewing machine attachment comprising a presser foot rotatably and slidingly mounted around a needle shaft, an arm extending from the presser foot construction, and a button upon the arm, in combination with a clamp fitting the button, an arm extending upwardly from the clamp, a plate pivoted to the arm, and a hook extending from the upper end of the plate to swing into and out of engagement with the needle operating mechanism; so that the presser foot may be optionally connected or disconnected relative to the needle operating mechanism.

2. The combination with a sewing machine having a head, a sleeve rotatably and slidably mounted vertically in the head, a needle shaft reciprocating through the sleeve a presser foot upon the lower end of the sleeve, an arm extending from the upper end-of the sleeve, and a button fixed to the arm, of anto swing into and out of engagementqwith the needle operating mechanism.

Copies of thispatent may be obtained for five .cente each-by addre Washington, 30 0.

3. A sewing machine. attachment comprising a clamp adapted for connection to a Presser foot, an extending upwardly from the olamp -a=plate'pivoted t0 the arm a hook extending from the upper end of the plate, and a set-screw screw-seated in the arm and adapted to engage the plate.

In testimony whereof I have signed my name to this specification. V
